Well they don't make a head bolt set without the .440 shank. and they don't make a stud set without a .510 shank. And the oil does get blocked off on some engines using studs. You can never tell me they all end up in the center of that .530 hole and smaller
You know All of this because some of you engineers just have to come up with a problem with how and old race engine builder improved the oiling on our engine. And all I wanted to do is share it with you all. This has been done for many years on many LA small blocks from Dave's shop , Other shops and my sons.
This was about a precise .070 slot cut in a dam head stud. And from the start not one member asked the depth or what else was done to improve oiling. Good night and may you all spin a bearing or two. LMFAO.
